Philadelphia Union's dream of winning the CONCACAF Champions League in their debut season continues.

Kacper Przybylko's late equaliser ruled out Santiago Sosa's first-half strike as the Union drew 1-1 at Subaru Park. However, Philadelphia qualified for the semi-finals, winning 4-1 on aggregate.

Sosa scored on the stroke of half-time as he managed to curl a shot into the far corner giving Andre Blake no chance.

Przybylko's late equaliser came following great work from Cory Burke, who did brilliantly to find the striker inside the area. Przybylko took a good touch before smashing the ball into the roof of the net from six yards out.

Jim Curtin made three changes after Saturday's defeat to NYCFC. Kai Wagner and Kacper Przybylko both came into the starting XI, replacing Matt Real and Cory Burke, who dropped to the bench. Jose Martinez missed the game through suspension, and Leon Flach started in his place.

Sergio Santos had the first chance of the game in the sixth minute. Jamiro Monteiro's through ball split the back three of Atlanta, and Santos was through on goal. He got inside the penalty area and shot with his left foot, but he dragged it wide of Brad Guzan's goal.

As he did, he shot towards the near post, trying to beat the oncoming Guzan, but it went the other side of the post, rustling into the side netting.

Philadelphia had another good chance through Flach minutes later. A nicely worked counter-attack saw Anthony Fontana pass the ball to Santos. Santos played it the first time, and it ended up in the path of Flach. The German midfielder tried his luck first time, but it was an easy save that was straight at Guzan.

Monteiro had a shot blocked around the 30th minute after some nice footwork to get past his defender. The rebound fell to Bedoya on the edge of the box, but his blasted effort was also blocked.

Mbaizo had another good chance in the 36th minute. A step over fooled his man, and he put the ball onto his right foot. He struck his shot with force, and it had enough to sting the palms of Guzan. However, it was straight at the Atlanta goalkeeper.
